RPM Meter / Digital Laser Photo Tachometer

Highly accurate, digital laser photo tachometer: measure rotational speed with a visible red light beam from a powerful LED. It's a great tool to measure the RPM of motors and machine parts, the speed of a lathe or milling machine for metal or wood working, or for HVAC applications to measure fan speed. To take the measurement, apply a reflective mark (included in package) onto the target object, aim the laser beam at the mark, the RPM displays on the LCD screen. Size : 180 x 72 x 37 mm (7.0 x 2.8 x 1.5").

DIY line Tracking Robot Smart Car kit

Working principle
Chip lm393 compared the resistor value, when there is an imbalance, the chip will control one motor to stop, while other motor accelerate rotation, in this case, the car can correct direction. The whole process is closed-loop control, so it can be quickly controleed
